Zusammenfassung:	Apparatus and methods for assisting a voltage regulator. In an example, a voltage regulator can include an error amplifier configured to compare a reference voltage with a representation of an output voltage of the voltage regulator, an output transistor coupled to a supply voltage and configured to receive an output of the error amplifier and to provide the output voltage, and an auxiliary-current circuit including a helper transistor having a terminal coupled to the output voltage, the helper transistor configured to turn on when the output voltage drops due to current demand from the load and to provide charge current to the load in addition to current provided by the output transistor.
